Definitions

  • the invention relates to a hammer plug, consisting of a plug formed of infection-moulded plastics material and a metal insert nail, which is pre-mounted in the plug over a part of its length, whereby the plug consists of a shaft adapted to be received in fitting holes in a base structure such as a wall or the like and in a member to be fixed against the base structure, such as a batten or the like, and a collar adapted to press the member with prestress against the base structure in the fixed position of the plug and whereby the insert nail over at least a part of its length is provided with a screw thread preferably a saw tooth thread, the collar and the shaft of the plug being provided with a substantially cylindrical bore up to a safety means preventing premature expansion of the plug by the insert nail, while the shaft beyond said safety means up to the free end of the shaft is provided with longitudinal slots for forming expanding legs, as well as with a substantially cylindrical bore with a smaller diameter than the diameter of the cylindrical bore before the safety means preventing premature expansion.
  • Such a hammer plug is known from GB-A-2 033 524.
  • the safety means preventing premature expansion is formed by a web of the plug shaft, against which the tip of the insert nail is lying in pre-mounted condition.
  • This hammer plug consists of a plug of plastic material and of the insert nail, which is inserted already to the web in the plug- Thus, plug and nail form one unity.
  • a continuous hole is drilled in batten and wall, the diameter of which is adapted to the outer diameter of the shaft of the plug.
  • the hammer plug is then inserted in the bore by hand as far as possible.
  • the lower side of the collar of the plug does not yet abut against the member and/or the member does not yet abut against the wall, since sometimes at insertion of the hammer plug in the bore a considerable friction has to be overcome, for instance by the presence of drilling rests in the bore in the wall.
  • expansion may be rendered inoperative, by which the insert nail is struck completely into the plug and the expanded legs clamp within the bore in the wall.
  • the plug will expand on the spot of the web and clamp in the wall bore, before the collar of the plug presses the member to be fixed against the base structure with pre-stress.
  • the hammer plug will not function then.
  • plugs are manufactured by infection moulding with an axial central mandrel in the injection die providing for the forming of the different cylindrical bores. By the presence of the web it is not possible to apply one continuous mandrel which makesdifficult the manufacture and makes it expensive.
  • the invention aims to improve the known hammer plug, and according to the invention this is obtained in that said safety means is formed by a shaft portion of the plug with a substantially cylindrical bore, the diameter of which being smaller than the diameter of the first mentioned cylindrical bore and larger than the diameter of the second mentioned cylindrical bore, which cylindrical bore terminates at the beginning of the longitudinal slots, after which the cylindrical bore gradually changes into the smaller cylindrical bore and in that the outer diameter of said shaft portion is smaller than the outer diameter of the rest of the shaft.
  • the safety means preventing premature expansion is formed by a conical bore within the expansion portion of the plug and a bead-shaped groove in the nail, in which a bead-shaped edge of the plug engages in pre-mounted condition.
  • the base structure generally a masonry or concrete wall is indicated with 1.
  • the member to be fixed for instance a batten for a slab wall or the like is indicated with 2.
  • a continuous cylindrical bore 3 is drilled in a conventional way.
  • the hammer plug according to the invention consists in the first place of a coventional metal insert nail. Its stem is indicated with 4, the head with 5, the saw notch in the head with 6, the saw tooth-shaped screw thread with 7 and the tip with 8. Obviously instead of a straight saw notch 6 also a cross saw notch or an internal hexagon may be present in the head 5.
  • the plug comprises a shaft 9 and a collar 10 and is manufactured of high quality plastic material.
  • the shaft consists of three portions, namely the portion 9a connected to the collar 10, the narrower portion 9b forming the safety to prevent premature expansion of the plug and an expandable portion 9c.
  • an axial cylindrical bore 11 is present with circumferentially a number of, for instance three or four, longitudinal ribs 12. These longitudinal ribs 12 are adapted for engaging the thread portion 7 of the insert nail in its pre-mounted position, as shown in fig. 1.
  • This portion 9b is provided with a cylindrical bore 13, having a diameter which is smaller than the diameter of the bore 11.
  • the transition between the bore 11 and the bore 13 is formed by a conical wall 14.
  • the cylindrical bore 13 changes through a conical bore 15 extending in the upper portion of the expandable legs 9c into a cylindrical bore 16 of smaller diameter.
  • the shaft portion 9b has an external diameter 17 being smaller than the diameter of the rest of the shaft 9.
  • the bores 11,14,13,15,16 in the plug form a continuous bore, so that during infection moulding one mandrel can be used, which moreover is self-releasing.
